Research Projects

Over the past three decades, quantum technology has led to the development of quantum devices, including quantum computers, quantum communication devices, and small-scale quantum appliances like quantum thermal machines and sensors. To achieve "quantum supremacy," noisy intermediate-scale quantum (NIsQ) devices made of 50-100 qubits are being tested for various quantum tasks, including hosting high-quality logical qubits. Miniaturization of machines, such as refrigerators, batteries, transistors, and diodes, is also being explored. The quantum states in these systems are characterized by quantum correlations like entanglement, quantum discord, and coherence. However, characterizing quantum machines using these correlations can be challenging due to resource-intensive state readout protocols and noise. The current project aims to modify the protocol for quantifying quantum correlations and test the results in quantum devices, including thermal machines and quantum codes.
